Implement Deadline Ranked Scheduling
...
This implements a minimal version of Deadline Rank Scheduling, as well as ways to access and set Deadlines.
This still needs some UX improvements, but is likely Enough for testing.

Add initial DRS scheduler placeholder
...
* Start hacking in cordyceps
This adds a third kind of runqueue, for now it should work the same as the
current "atomics" runqueue, but uses a cordyceps TransferStack instead of
the existing home-rolled linked list.
* Clean up, use new cordyceps feature
* A bit more cleanup
* Update docs to be more clear

Before, enabling `trace` would enable embassy-native tracing, and
enabling *both* would *disable* embassy-native tracing.

embassy-time: add missing Debug & defmt::Format derives
...
`defmt::Format` is *not* implemented for `MockDriver` and
`InnerMockDriver` because the former contains the latter and the latter
is using `Queue` from `embassy-time-queue-utils` which so far does not
have a `defmt` dependency. since this is just a mock driver it shouldn't
be relevant if it has no `defmt::Format` impl.

executor: Make state implementations and their conditions match
...
Use u8 for state_atomics and state_critical_section since that
is all that is needed. Change arm condition to "32" since that is what
is used and required.
